Recessed lighting

I noticed at the orange home improvement store that there are two main categories of recessed lighting -- 1) kind of expensive, and 2) really expensive.

It seems that the former is 110 volt, and the latter is low voltage, requiring the expensive transformer. If I want to add 10 to 12 recessed lights throughout the front rooms of my house, what are the things I should consider when deciding whether to go high or low voltage?

I know that the low voltage lights need special dimmers, but that's about the extent of my knowledge. There is no insulation in the attic crawlspace, so that isn't an issue (currently).

Thanks

Low voltage halogen lighting excels at task and display lighting. It's worth the price when shining on paintings, sculptures, crystal, glass, you get the idea. For general room lighting the line voltage fixtures are more cost effective and do a fine job.
