I've been reasoning to myself for the last few months that I don't need a indoor trainer since I've been happy doing my 50-100 miles on weekends. I now would like ride 30min-1hr ~2-3 times during the week too but from out my door I can't really get to a good pace without stopping every few spins to check/wait for traffic.

So, I'm now thinking of getting indoor rollers or trainers as a christmas gift for myself

As far as I've searched on google (the BF search function needs to be fixed, I only get 10 hits of which only 1 has trainer/roller in the title), I think a set of Rollers work better for me. Here's my reasoning:
(1) my bike handling skills need to be improved, (I can't hold really hold a straight line well, at least from what I can see and especially while climbing)
(2) I can't even keep up a 90rpm cadence at my maximum speed gears while on a flat.

So I reasoned that a roller would benefit me more than a trainer for now. I'm happy to hear suggestions otherwise.

My questions:
(1) Can I get a good workout in ~30mins on rollers? (I think the answer is yes, just checking)
(2) more importantly, any recommendations of Rollers that are <$300? (Kreitlers cost an arm, I don't need the best, just durable for a few years)
(3) What size Roller drums should I start with?
(4) Are they really noisy? (I'm using this at 6am, living in a townhouse with a roommate, can't be too noisy)
(5) are these nashbar branded ones good?
