I gave Focusrite the mental boot years ago. If nothing else, almost anything is going to be a rather huge step up from what you're using (geez, I don't mean to sound harsh, but those penta/platinum things are just awful... Can't believe they actually put the word "Focusrite" on them).
Budget-friendly -- Grace m101, True P-Solo (a personal favorite), FMR RNC.
Much nicer without breaking the bank -- API (the A2D is a hidden gem), Great River, so many others. Even the Focusrite (the relatively "real" stuff anyway) isn't too bad.
King of all mic pres -- Crane Song Flamingo. Freakishly amazing if it's in the budget.
