i've been to most over the years to set up my cossy's
had a bad experience with ava once
that said been there loads of times and only ever had 1 bad experience with them so maybe just bad luck
they are very expensive imho
andy g's doin good stuff just now, usualy good with prices as well
couple other places around as well but think i'll be goin to msd for a live map when mines ready
gonna be worth the run down as i've only ever heard good stuff about them
just depends on what your wanting done realy
pm me what your after and i'll give you my advice on the best place (imo obviously)
