You could also look at the Vantage Audio feet which are only 25 quid - I preferred them to Isonoes in my rig tbh. YMMV of course but they do work very well, and are adjustable too. With the Achromat you've got a decent jump in performance for a smidge under a ton.

The 1210's a very talkative bit of kit, in that each mod you can make to it, it'll be obvious as to whether it works or not.

Most of all though - have fun!

Any one got a link/piccies of the Vantage Audio feet?
