My amp is 40watts per channel and it handles the m22's fine. When looking for equipment I've found that it pays to do an exhaustive search using google. I've also found that if in the US you can save a lot be purchasing through Canadian dealers.
One sight in particular if you're looking at Cambridge Audio is http://everestaudio.com/ remeber there prices are in Canadian. Some prices include shipping, but call first. Another great place is the AudioShop in Ottawa http://www.audioshopcanada.com/ If you're considering Axiom speaker definitely give them a call. They sell them so they can really help you with matching them to a good amp.
The money you can say is not little either. My brother-in-law just ordered a new turntable for $250 less than he would have paid if bought locally.
