Newbs! If yer thinking of getting a shutter, why not save yourself some cash and get a Spyder E99 instead, they are basically the same as a shutter, but with an electronic grip frame, and a few cosmetic parts removed, and about £40 cheaper.
I have one, and out of the 4000 rounds put through it so far, can't remember any breaks. The stock barrel is relatively good too. Plus, you can't beat 1mm travel on a trigger (IMHO)
, and it beats buying a shutter, then deciding you want a electro frame and having to shell out another £100+ for something you could have already had, cheaper.
Altogether, from my experience, the shutter, e99, and i guess the TL+ are good guns, all easily stripped/cleaned/maintained and have given me no problems. You wouldn't go wrong with a Spyder.
