I use Aliexpress all the time. If you can wait for delivery, wait for the specials and want some low cost stuff it's great.

Down side is waiting for parts to arrive. It can take months and sometimes not at all. But their dispute and refund process is excellent. I got my Tone Pro bridge from there and it is quite good. BEWARE!! You can spend hours lost in there.

If you want quality pick ups, pots, cap, etc (the things that REALLY matter) then stay with PBG.
