if you're just looking for a good C stand with a small boom, i'd recommend the one made by impact
Impact Master Century C Stand Kit with 42" CT40MKIT B&H
its a very solid stand, just make sure to take advantage of the c stand design and throw a few sandbags on its legs. They're not always necessary, as its a pretty damn solid stand, but peace of mind is always nice to have.
If you want to boom out further than the 40 or so inches that the stock boom provides, I recommend splurging a bit on this purchase. Make sure both the boom and grip head are of high quality, as I've found out the hard way that cheaper booms and grip heads can barely manage the weight of a bare monolight, nevermind modifiers. Manfrotto makes a pretty damn solid boom arm:
