First post and thread in the section. 
So you want to buy a Tech2 for the ability to do a lot more than just read codes. There is now a proliferation of clones coming from China of this tool. Some of the earlier ones were prone to failure but I think the quality has increased while the price has been steadily decreasing.
I bought mine from this seller at Alibaba:
http://www.aliexpress.com/store/product/Auto-Diagnostic-tool-gm-Tech-II-GM-Tech-2-Pro-Kits-for-GM-SAAB-OPEL-SUZUKI/1756517_32313222529.html
It comes without the carry case but I didn't really care because most have broken hinges anyway. I used an old laptop bag that's perfect for all the cables and attachments. Shipping was quick. It came within a week. The seller is very responsive and answered my questions within a day. He also put the value for customs at $45 so taxes and import charges were minimal.
Have been using it a few times and it works perfectly except that it reboots when I start the engine. Not too sure what's up with that but I have a feeling that the drop in power may have something to do with it. Apart from that, it comes with everything, including the TIS2000 software but no dongle but there is a crack available to get that working.
If you are willing to wait, it goes on sale for 5% off once in a while so save it in your wish list and you'll get an email that it went on sale.
