I etch then drill but then I'm not doing plated through holes. To do a good drilling job you really need a drill press and carbide bits. the HS steel ones just wear out too quickly though the aren't as brittle as carbide. You can get a small drill press for well under $100 and the dremel kits are reasonably priced, too. Because a drill press has a lot of other uses, I see it as a no-brainer acquisition. I use a cross sliding vise with my drill press. once I have the vise lined up and the board aligned to the vise it becomes very easy to drill holes with in a few mils of the target. Still, I hate drilling. Its the worst part of the process for me so I bias towards surface mount components. Mixed through-hole and smt works pretty well though you will have to do more vias.
