the video demos are not impressive... maybe just bad choice of demo tunes. (have nothing to to with Gilmour)
if you are really after pink floyd tone I think the DG20 is the way to go - I remember that not long ago they were on sale at amazon - cant recall the exact price but it was not that far from 130 bucks.
also if you like the pink floyd - gilmour did use a regular strat at that time
here is a link about it
queen - may's guitar if very far from strat (or any other guitar lol )... I've heard live a strat with brian may mod's - Tri-Sonics wired the way they should etc. It sounded great...but nothing like queen
I recommend this video :
and this site http://treblebooster.com/brian_may_pickup_mod.htm
vintage tone - there are a lot of pickups for that on the market so I'm sure the guys are going to give you some good advice.
one more thing :
not long ago I installed these pickups http://www.entwistlepickups.co.uk/pi...hp?puid=ASN+57
on affinity (they needed some routing because they are a bit fat and the affinity is a bit thin)
I ordered them online from some chinese site (at least they were shipped from china I think...did not really care to look at the stamps) so I don't even know if they were the real thing or not - they were something like $20 or $25 (for the 3 pickups) and they sounded great ... took forever for the delivery tho
so there are a lot of options
