1) As you're finding out, good pro audio gear doesn't lose its value like cameras do so you end up paying a lot more for it. The benefit is that it will hold its value for a long time to come.
Check the used sections of pro audio shops such as Trew Audio, Location Sound and Professional Sound Services, just to name a few. They deal with gear like this every day and have a lot of used gear for sale on their sites.
For example, if you're willing to settle for a Sound Devices MP-2, Trew Audio has one with Portabrace case, top pouch and shoulder strap for $675.00
2) Porta-Brace has the MX-24 MINI case which is supposed to fit this recorder. I can't find any dimensions on it anywhere but the shops listed aboue should be able to help you. They may also be able to recomend another bag.
