check
http://www.pbreview.com mate to see what people think. The best way to see if you like a marker is to shoot it tho
.
The shutter looks nice but IMO the ones with the vert feed are better, but the rear cocking bolt is a bonus (i prefer these to side cocking ones)
you will need a new barrel on it tho as the stock barrels tend to suck and maybe paying a bit extra for an electro handle and an electro hopper.
Check the classifieds all over the place cos you can prolly get an upgraded setup cheapish, and guys tend to look after their markers.
I like my spyder because i am learning how to play well and learning marker maintenence. Its all about budget and personal preference at the end of the day. (my E99 Avant is my first marker and i love it
)
