What are your current system specs?
There are several interfaces available that would serve you well and fit your budget.
Many have multiple inputs with phantom power. The Focusrite Scarlet series come to mind. You could kill two birds with one stone.
Also, if you are recording softsynths with live keyboard or e-drum input, a decent interface is a huge plus.
You have lots of options in your price range.
My own system (Yamaha MG10/2 mixer handling the front end for an E-MU0404PCI interface) has met my needs nicely, but it is fairly humble by today's standards.
