I have the Oster Fast Feed and Classic 76 since I'm a baldy. Only the Fast Feed is in your budget.
The 76 cuts closer (same blade), has more power, cuts smoother, and is easier to clean. I only got it a few weeks ago though, and while it cuts good, it doesn't glide as smooth across your scalp if you're going for the buzz because the blade isn't mounted/fixed to the clipper.
Fast Feed is good, but uses a "cheaper" motor that vibrates more. I used that thing for a year, and it cuts good, but I've had to pass over spots more than once. It glides smoother because the back-blade is mounted directly to the unit, and only the lower-blade moves. Thing resonates my skull. For half the price, it's not remotely bad.
