Guys, thanks for the advice. I thought it over, then posted my stringer for sale and it went right away locally. Then I cleaned out some old frames. Now I'm about $150 off one of these:
Once I sell a few old golf clubs I'll have an even swap and a cleaner house.
Along the way I almost purchase an Ektelon Model H, but someone else purchased it an hour before I got to the seller, for $239. Live and learn.
I wanted a good quality electric with prestretch, and I think that's what I'll get with the Gamma. Thanks for the advice again -- I'm glad I didn't take a flyer on the Wise.
