That was my first choice over the HG/BM because I'm not too handy.
Only makes sense.
As to greens prices at Sweet Maria's, they're very reasonable and extremely competitive. I don't know what you found for $25, but it probably wasn't a pound of coffee.
SM has a few very good, well-chosen blends of greens for espresso that don't take a lot of complicated profiling. While you're learning the difference between C+, FC, and FC+ at least you'll be able to drink the results without gagging. I think Monkey is a particularly good beginner's blend; not only that you'll find yourself returning to it as a good, all-round, US style espresso.
Like just about everyone, I've been very happy with SM. Besides everything else, their (Tom's) descriptions are so very valuable.
Another good source for beans and machines -- not to mention the discount sampler pack with a machine -- is Roastmasters.com.
There are a bunch of other places that are good for greens. But for just starting with espresso, you're probably best off with a blend put together so it can be roasted already mixed.
