Should I sell my LR Baggs M1A Pickup?

[Vedt]

I purchased it new last spring and had it installed in my cheap, Ibanez acoustic because I had a few gigs scheduled. Since then, I've purchased a "real" acoustic - Martin OM28 - and had a K&K pure western mini installed.

So I'm thinking of selling my M1A pickup. I can't see ever using this again, unless I were to purchase another acoustic for back-up. But part of me is hesitant to sell given that I paid $170 new plus $90 for installation. I doubt I can get anything more than $110 now.

Any regrets in selling yours? Or have you found that the M1A is way better than other invisible pickup systems?
