What had you go with a Derale? I've been looking at a few, and I see Derale, Hayden, and B&M. I'd like to get a good quality, but also one that fits easily. I don't tow much, and I don't run in desert heat. I just figure that $50-$75 is a pretty good investment to lengthen the life of a very expensive component.
You don't need to tow, just keeping the fluid temps in check is reason enough. However, most members here, including myself, have surpassed 200K with no extra cooling. But, I don't like replacing expensive parts or components so I wish I had added a cooler earlier just for peace of mind. I went with Derale because they have a wide variety of applications, well-respected, and mainly the size of the cooler because I wanted a stacked-plate so i wouldn't need a larger tube to fin cooler...the stacked plate is more efficient.
$50-75, or even $100 is very cheap insurance indeed, I agree. Also the best thing to do is keep your fluid flushed every 30-40K, there are fluids that last 100K but regardless not all tranny's are the same. Change the separator plate at around 100-120K is cheap insurance also.

I see on the Derale one that it, "Includes line adapter to eliminate cutting transmission oil lines." Was it a simple line swap?
The line adapter will fit, but I used the stock cooler line since it's bent at 90 deg and keeps a clean install. The line adapter is straight and the hose won't make a sharp bend so the entire outlet connection will extend father than I felt comfortable with. Cutting the line isn't bad at all and is a nice, clean install.
I bought an extra cooler line from the radiator outlet port back to the quick connect on the frame near the power steering pump just in case I screwed up. I took the stock line off, then cut it about 12" back from the outlet. I put a slight flare at the end so the hose would grip, I recommend this. If you don't flare, then be sure you push the hose on about 2-3" and use 2 hose clamps,

One that I was looking at was the B&M 70268, as it passes thicker fluid back and thinner fluid it runs through the cooler. But as I think about it more, I'd rather K.I.S.S. Now I'm looking at the Derale 13102 and the Hayden 403 or the Hayden 678. But I think the 678 does about the same thing as the B&M. Got to research more.
So - what did you base your decision on?
I was going to go that route, but I wanted a simple cooler, the stacked plate cools with a smaller unit as well as a larger generic cooler. Keep in mind you want the fluid temps warm enough for proper trans operation and moisture evaporation. The Derale 10-row unit fits perfectly on the drivers side, just needed to take some time with a couple angle brackets from my local ACE since I didn't go with the Derale mounting bracket...probably should have.
The 4' hose that came with the cooler wasn't long enough, I would recommend picking up another 4' of hose to be safe, you will have a little excess. I was going to get another larger cooler but I didn't want to block the AC condenser any more than I needed to, our AC struggles as it is sometimes.
I believe any cooler would work well, mine won't keep the temps from climbing in extended stop and go, has seen around 190 with the cooler but at speed it's generally 170-175 which is much better than the 200-205 I was getting while driving. Without the cooler in stop and go my trans temps were 205 easily.
I have mine mounted about 2" in front of the condenser, I may experiment and mount it flush against the condenser later on to see if that improves cooling in stop and go traffic since the fan may have more of a positive effect on airflow with it being flush.....dunno.
