Now now, let's not go crazy. Never confuse inexpensive with cheap.
Pyle if short for the Pyle of steaming, smelly, brown stuff the dog leaves on the grass.
In "cheap" vintage isn't your bag, NAD and Marantz make quite good two-channel only amps (and receivers), as I'm sure others do as well.
And, try to avoid tiny speakers. The sub should only fill in the low end and the lower the mains can cleanly go, the better the system you'll wind up with. IMNSHO, I won't consider a main speaker with less than a 6 1/2" woofer, but others may disagree.
[edit] Nearfield, you say? That's some mission creep there. Lemme think about that, but consider a "real" amp. Those tiny toy amps run out of power quickly. Your sub is gonna overpower it, and tiny speakers as well.
