FP is definitely still around. I know he's probably pretty backed up order wise, but I also know he's very close to perfection on several new projects that should surface soon. Don't think he'll have to worry about redoing his current helmet or armor molds as they're pretty much perfected, except for replacing worn items over time line ear molds. Very high quality items.
Bobamaker makes good props and is reliable. The helmet looks a little small IMHO, but it's a nice job. Haven't seen his armor or gauntlets but I do have his Jango knees and they're very nice.

Sure there are others, these are just the ones that come to mind.
Definitely don't rush into anything. Stop and smell the roses and read. Lots of info to digest before you go dropping lots of money.
