ok seriously how did this end up a tube vs ss argument....i think most of us should be able to realize that there are good and bad tube amps just like there are good and bad ss amps.
I will have to agree SS amps are much more reliable than tube amps, and SS usually don't crap out on you so easily. Tonally SS and tube amps vary greatly but just about anyone with common sense will realize that. But at the same time SS can be much more versatile than tubes.
Play a Roland Jazz Chorus, old Musicmans, Fender Mustang, etc and see for yourself how far SS amps have gotten.
I really don't see why you are arguing over something so petty when it comes to low cost amps usually SS amps do sound better than cheaper tube amps. And the Fender Mustang III, IV, and V are actually pretty nice sounding amps, this is coming from someone that gigs with a tube amp regularly. I came pretty close to getting a bigger Mustang based on owning a Mustang I as a practice amp for my apartment, I tried the bigger versions when I was auditioning various other amps for gigging and I have to say the Mustang can hold it's own with the amps it models.
I think for low cost Solid State Fender Mustang amps win the contest for current production amp heads.
I think for a low cost Tube amp your best bet is likely an Egnater Tweaker for a current production amp head. As this amp allows you to drop in just about any type of octal power tube and you have three distinct EQ voicings, vintage/modern switch, normal/bright treble switch, and a tight/deep bass switch. Plus having gain and master volume gives you any number of tones from clean to all out mayhem.
Another suggestion would be Blackstar HT1, HT5, HT20, or HT40.
I'd rather have an amp that can handle a lot of tones personally but I play jazz, country, funk, motown, surf, rockabilly, classic rock, etc.
