I have never tried any of those, as I have said to you in our previous IM Chat session that its hard to stay with one free hosting service for a long time, free host is very good, but you have to work hard to get ur account...
Personally i have used these 2 service previouslly,
1. Mihopa >> *mihopa.net/forums/
Unlimited Bandwidth, and frndly hosting so if u are using more that alocated disk space, they dont mind

, I fav Free Host over the years, also it was my 1st free hosting service...

Major down side is, too much of
Down Time
2. DX-T Hosting >> *www.dx-t.net/forums/index.php?
Good over all feature, Problem is same like Free Host hard to get that hosting and you have to post a loot at their forum...
So tell you some thing, with free hosting, its you who have to try and learn whats best for ur self, we can only suggest some options... !!!!
