I've bought both good and bad cheap scopes off of Ali express. My BSA side focus 8-32x44 is very good as is my diana 4-16x42ao (mine has an etched glass reticle - most seem to be wire rets!). Another BSA 4-12x40 was rubbish as was a side focus 30mm body scope. Do not forget the rules re VAT as well - the VAT and £8 vat collection fee can make a good looking deal less good!
This is the BSA - range finds well and good enough for FT. A UTG side wheel fits with a bit of adapting...
