Rear shock absorber

Hi all
I'm looking to buy a uprated rear shock but I'm not sure what to go for & would be interested to hear peoples opinions... Currently using a standard escort which has served really well but I'm moving up to a Ts1 so could do with a better shock to suite the extra go.... In the past I've tried a fancy pm shock but its a bit out of my price range (it was good tho).People have suggested R1 or R6 converted shocks but I'm just not sure I want to pay good money for something 2nd hand..Any info/ experience gladly accepted..
Cheers Mark.
