im looking for some good pickups for my MIM HSS Stratocaster. I have a low budget. Can anyone recommend me some really good ones or atleast good compared to the competition at its price range. thanks!
Bill Lawrence pups are really good, also look on eBay for pups.

Also, go to seymourduncan.com, and listen to all of the sound samples and see if you like any of them.

As far as specific pups, I can't recommend unless you tell what kind of music you're playing, what sound you're looking for, etc.
I got some SD Sh2n and SH4 Jeff Becks. Sound fantastic and very versatile. Sadly, you cant test pups before you buy!

they cost me $110 from America recently. Which is ridiculous, given theyre the equivalent of about $250 here in UK.
