4 Speed w/ Overdrive Any Good?

I had a aluminum cased OD 4 speed behind a 68 383 that was hopped up and had 3.91 and then 3.23 gears, it held up just fine. I bolted up to the 68 bellhousing with no problems and ran it for a while in my 77 lil red clone when I was about 19.
I paid $75 for that one and I just got a cast iron cased OD 4 speed a few months ago that came with a shifter, bellhousing, flywheel, and 2 new clutches for $150, Don't pay anything over $200 for an OD 4 speed!
