Where is the best place to buy a clone GM tech2?

Today, I visit http://www.saabcentral.com/forums/ and read an interesting topic: Where is the best place to buy a clone GM tech2? a reliable site or Ali or ebay?
I think it is something helpful to the newbie who are looking for GM tech2, so I'd like to put together some typical posters' reviews. I declare all posts are original not by modified.

1. I bought my Tech2 from this site. They charge more than the sellers on AliExpress but I was able to use PayPal and had no issues with payment or shipping (got the package a week after I ordered it). I certainly wouldn't want to send copies of my driver's license/ID to buy something online.

2. I have recently purchased a tech 2 clone with 148. Downloaded all the software I found on the site and have a working tech 2 with security access. I have done DRL turn offs through the reading and knowledge of gturner's help and experiments. I successfully replaced a bad ecu with a stage 1 I received from MPS and now have a damn good car. This site rocks I have obtained a lot of knowledge from all the guys that have been experimenting. I live in Texas near Houston and was stuck out do to no place to get the change done except through a GM stealership who would have charged me 7 to 800 because it had to be an ecu they got, labor, and usage of the tech2 and tis.

3. So I got the TECH 2 on Friday on eBay and spent the weekend with it. All is good and works great. Super quick to respond and it got here in great time. I ordered it without a case because I have old plastic tool boxes and foam so I'm just gonna DIY a case for it. The only gripe I have is with the connectors. then need some modifying in order to clip in and stay locked in place.

4. I can use my tech2 clone from aliexpress to everything on my three 9-5 from -99, -00 and -01. I haven't experienced anything that stops me from using the Tech2 at it's full capacity.

I have programmed keys and remotes which must be security related. The Tech2 has never been connected to a computer in any way. 

To sum up:

Where is the best place to buy GM tech2, it depends on not only price, but also payment option, shipment, after-sales customer service & tech support. More importantly, is it working as it claims.
