It would help if you indicated a budget - but assuming 2nd hand and you have say FTP money then the world is your oyster!
AR20 - £500
MPR - £500
EV2 mk4 - say £700
Protarget with a custom stock - or even in an EV stock similar money maybe even cheaper. - My choice as a starter
steyr 100 0r 110 £800 - 1200
FTP 900 1000 to 1200
Don't forget to save say £3- 500 of your budget for good glass!
