Haha. Mine's been against the wall for the around the same time.
Maybe we should dust from time to time?
I think so.
The unit Ecc is recommending would be totally fine for recording your piano, and I'm not knocking it, but I'd keep expansion in mind.
If you decide you want try try midi some day you need a third box, and if you decide you want to sing or record acoustic guitar you need a fourth box, or maybe fifth?
If you think recording is going to be something you'll keep tinkering with I'd get an all-in-one.
Something with speaker outputs, headphone outputs, mic inputs, line inputs, and midi I/O all in one box.
Your recording software will thank you for keeping everything in one box.
That sounds like a lot of ins and outs, but it's pretty standard.
You have the benefit of all your cables running to one place, once neat box on the bench, and, usually, reliable quality drivers from one manufacturer.
Some of the usual suspects for starting off are Presonus, Tascam, Native Instruments, Focusrite.
Personally I'd recommend looking at something where the line inputs are separate from/additional to the mic preamps; I.E. Something with four analog inputs.
Only you know your requirements, but it's usually nice to have those options as separate things. (keyboard and microphone live, some day?)
Hope that's helpful.
