I’d probably vote Eclipse in the first instance, they specialise in magnetic stuff so very much their thing. I’ve got two, both superb, but appreciate they are a British firm, so not sure what the availability is like in the U.S. Starrett would be, in fact are, very similar.
Don’t think you don’t need a decent one if you are a ‘weekend warrior’. The decent ones are just so much nicer to use. But... another vote here for buying used. I have two magnetic bases, a magnetic V block and a magnetic chuck, all bought used without any issues, and at a huge saving!
Alternatively, I might be tempted to check the MSC specials. Here in the U.K. decent bases turn up on offer quite often!
