MAP on the A styles is about $325 (I think) and on the F styles is about $275 (I think). I liked the sound from the A styles a little better, so we tend to stock more of them. Model numbers for those are KM-160, 161, 162 (sunburst, black, amber). Right now I'm out of stock and they are on backorder. If you're considering A style mandolins, I'd look hard at the Kentucky KM-171, 172 or 174 (black, amber, burgundy). By extrapolation (always risky I know) I'd say that the SF-200 would be OK ($299 is the MAP on that one), but if you could squeeze out a few more dollars, there are others you would like a LOT more. We did have one tuner button split on us once, but other than that, they've fit the bill very well for what we wanted 'em to do. Sounds decent, required only a tiny bit of setup adjustment to be very playable for inexperienced fingers and felt like it could take a bit of abuse. In my opinion, for the cost ($200 MAP including case), it is a heckuva deal for a beginner mandolin player on a really, really tight budget. However, we do carry the Savannah SF-100 model. Yeah, they cost a bit more overall, but the step up in quality over the Savannah is significant.
I think part of the reason was that by the time you added a case to the price, I didn't think it was quite as good a deal as some other models, such as The Loar LM-500-VS (MAP is around $475? if you can find one) or some Kentucky models. I'm really not sure why I didn't pick 'em up, but I didn't.
We don't carry this particular model as a rule. That said (disclaimer coming) we are dealers for Savannah mandolins, among others. What's the budget? I know you mentioned $300-400 range, but could you stretch a touch more if it got you a better return on your mando bucks?
What do you plan to use the mandolin for? (bluegrass band, knock around the house, celtic?) A couple of quick questions for you so that we can help to give you a better answer:
