I have been lurking here on head-fi off and on for several years and read I don't know how many threads lately for the past few weeks... I have finally been looking into getting some entry level stax but I think my initial budget (which was originally for some mid level senns) is probably too low (<$200). What is a reasonable expectation to have for an entry level set of stax (or other electrostatic perhaps) headphones and either an energizer or amp?
It looks like amps tend to cost quite a bit more and I do have a receiver I could use for now with an energizer. The main thing is, I intend to use this at work (closed office door so sound leakage isn't a problem) and I plan on having them on most of the day so they need to be comfortable (amusing that this issue has been discussed recently). For me, that usually means circumaural. From my understanding, the lambdas are, as well as the gammas/alphas. Are there any other stax that would qualify (in the lower budget range that is

, I doubt it's worth discussing the higher end in this case! ) I've been unable to tell for sure if the SR-3s are or not.
I'm OK with them not looking perfect as long as they sound OK, but I'm not sure how much that would tend to drop the price if at all.
I've read conflicting comments on whether gammas (which appear to possibly be reachable in my range, at least I had found some historically) are worth it sound wise compared with lambdas. This would be my first higher-end setup so in truth I'd probably be happy with even the lower end stax...
Thanks for any help!
