Questions on spydermag Frame build

[RoMan]

i found a few cheap spyder frames and was thinking about undertaking a project to make a spydermag frame. Which one of these would be the easiest to convert?

its hard telling without seeing the internals, but if they are the same inside as a stock spyder e frame then either will work. I like the looks of the smartech one and i may pick one up to. ive also been wanting to make one, but the solenoid is stuck in my stock frame...
