Thanks for the mention! However, I would avoid the TGP gallery game if you were limited on starting $ or time. It's a daily grind (like most jobs) and $200 wouldn't be enough to buy a decent server, submit tools, and partner accounts. I would say the monthly minimum expenditure for TGP submitting would be about $400/mo and you should be able to get much more than that in return IF you submit every day. I've got it nailed down but for comparison I can submit 5 TGP galleries a day in about 2.5 hours. A newbie might take 2 or 3 times that in the beginning.
To your original intent, if I was you with free sites and $200 to invest (assuming you already have a server), I would first buy the
Chameleon LL submitter to help with building the pages and recips. It also helps submitting manually and/or automatically. It's a huge time saver and expands your free site exposure. Tommys Bookmarks PA would also be a good purchase.
You should also have some blogs/hubs to link back from your free sites. Those are ~$8 per domain and your time. Build a network where any surfer you catch will be able to find something on whatever niche he likes.
