Well here's what I would do.
I had the Frontman as my first amp too. It buzzes like a hornet's nest and sounds like a cat throwing up.
If the only thing deterring you from getting the Vox is the grill cloth, I suggest you buy it with another grille or make your own.
This site lets you buy it for only 40 bucks more with a new grill cloth.
You could also make your own grille and add the cloth. This isn't too hard, as you take out the chain-link fence that's in your amp, cut a piece of particle board to the same size, whack a hole in it, cover it in the Vox stuff, then stick it on.
I was fine with the metal monster, but both these are good options. It is a great amp, and It would be disappointing to me if you didn't consider it for looks (no affiliation with Vox or north coast music).
