Hi. I'm newbie in domain biz but not that new to webmaster sh!t.
Avoid free hosting. And for god sake, avoid subodimains under free hosts. About 1 year ago I've just tried freehostia (5GB/month), quit good for free, just have build my first newbie webmasters guide blog, just for kicks, but I've made some promotions and I've got PR1 and about 15 uniques /day - not much but I've got some good referrals that are earning me some money for months. But now my old unmanaged blog is dead, nobody know why.
I have some good friends in webmaster community that have started with blogspot with adult blogs with free content hosted on image, file and streaming hosts. When they got >5000 uniques they mostly got reported and sequently banned.
ALWAYS be ON YOUR OWN else You're lose Your sites one day.
For example, with Servage (sucks but what can You expect for such few $).
You have 5000GB/month (they expect You don't spend it all, especially when it's 170GB/day not 5000/month annually)
You got some 500GB of storage, You don't need that much and I'm sure You can't go to 100% of storage

There's 400,000 hit (element load) / day limit (might be higher since every parameter in servage grew since I've lasted knew this info).
You got 1000 MySQL's, You can put dozens of domains under one account.
Biggest problems are downtimes, especially when using MySQL.
But for 6,35 EURO + VAT (if non-european it's 6,35 DOLLARS) if You pay for 14 months and You'll get one domain for free (don't pick domain you really want cause it will cost You 25$ next year).
so for about 100$ + VAT (if You pick seychelles, it's without VAT) You have reasonable host for 14 months and can host tons of domains there.
There are plenty of similar cheap shared hostings but mostly have higher CPU usage limits.
