A tricky one this. My bonus is just about to hit the bank and before 'er indoors allocates it all to 'projects'

I though I might get in there

and commit spend to something that _I_ want

And she generally approves of my archery, so it won't be a big battle
Now I've had a bit of a long standing desire for some border limbs, and I do need to upgrade as I'm currently fully cranked in. But... Would a cheap compound bow give me something to play with? Given my limited budget (c. £500) would I get anything worthwhile on the compound front? Or should I just stick to the to getting some new limbs for my recurve?
Thoughts anyone?
