Thanks, everyone, for your input. I decided to go with the Ampeg, not only based upon your recommendations, but upon a couple of other factors. Ampeg is, of course, well known for their name and sound, regardless of whether or not they are the same company now as they were decades (or even 10 years) ago. No one that I know of in the bass world has achieved that "Ibanez bass amplifier sound."

And I do tend to like the old school sound, even if it is in a fairly small box. The other factor is that I probably won't have any problem getting my money back out of the Ampeg, even if it is a combo. Hopefully, in a year or so I'll be ready to upgrade to mid-level hobby 300 watts or so.
