Which one is recommended:
Prefamac Guitar Cutter, Bakon USA, Martellato, Dedy, JKV ?
As mentioned previously.. don't get the Prefamac, as it is just the Dedy guitar cutter with a Prefamac branded plate on it. They also force you to buy four cutting frames, whereas with Dedy, I think you can buy individual cutting frames. Go for the Dedy.. lovely bit of kit.
When I bought my Dedy, it was cheaper to get it with the 4 frames than buy it with one or two frames, separately. Check it out with Tom at TCF sales, he sometimes has them on sales, ask for a small discount. Don't tell him I said this, LOL.
