For the money, even factoring in the extras I think these tiny amps are astounding for what they cost and I'm satisfied to use this amp in place of several other D class amps, a nice 8 watt SET tube amp I've had for many years, and my venerable old Adcom. Is the tda7297 the best or final amp I'll have? Probably not, but for now it'll do nicely. It really rocks and I listen at loud realistic volumes. Well worth your time to investigate.....
I agree is there a particular website/vender on aliexpress?, had some vender that did not deliver on aliexpress...

By typing in **TDA7297 diy kit** in Aliex search box I came up with several entries for around AUD1.85. I didn't buy from them because they don't accept paypal, and filling in all my banking details for a couple of $$ isn't worthwhile. I have used Aliex many times in the past with no issues at all, but for a couple of $$ I use Ebay, where I can pick up those TDA7297 for around AUD4.50, which is still cheaper than dirt...
