Advice on media blasters...which one?, Let's go shopping... Options

[computers4kids]

I'm looking at a variety of media blasters at Harbor Freight and could use any insights/experience to lead me to the best purchase for my needs (below).

A:
I have come to a point in my project that I have the underside of both trunk lids and the door jambs that need to be prepped for paint. A real crappy paint job was sprayed on at one time. (rest of car has been stripped, reworked, sealed)

B:
Lots of little parts that I would like to bead blast and paint/powdercoat before the car goes back together.

C:
Picked-up a set of 2ltr alloys that I would like to bead blast the backsides to clean-up before I polish them. Not to sure if I should bead blast the front before polishing. I'm not going to send them out. Last set I wet sanded and polished the hard way, but they turned out real nice. Not sure if bead blasting would help or make more work for me.

Here are the choices I have and current prices at HF..some on sale.
