Here is my my Spyder project marker. It's in the under $25 category.It's not a Spyder per say, but a Raptor. I removed the powerfeed and made a low tech (crappy looking) spring feed magazine for it. I used a binding spring from a spiral bound notebook as the magazine spring, and low and behold it actually works. The body and barrel were bead blasted, but thats as far as I got due to work.The grips were made out of Walnut by me. I was planning on making a drop in Walnut stock for it, but I ran out of time due to work this month .

Here's the rundown on the cost.
1.I bought this marker from Dan Bacci last year for $15
2. One spiralbound notebook for use as a mag spring $.89
3. Everthing else I had laying around or did myself.
Now how about an extention to finish this?
