I've just started to jump into the solid foods arena, and while it's easier than I thought (save the constipation issues), I can definitely see the value in a compact, all-in-one device to help you make your own baby food. The very popular in France, BPA-free Beaba Babycook ($150) steams, purees and even reheats or defrosts if you make in bulk and freeze. The bowl and basket are dishwasher safe and it also comes with a spatula and recipe booklet. It's new to the U.S. and yet there's 30+ glowing reviews at Williams-Sonoma.
