Party mtt's - Quality of field

I've search on this but not come up with much.

What is the general consensus on the standard of the NLTH mtt's at party, $30 to $100 buy-in?

I've started playing a few while playing my usual sngs, and I find them pretty fishy. Often having an average stack approaching the bubble without paying to much attention to the play, but only played a handfull so it's hard to know the real standard.

Also are the higher buy-in weekly games $200+ much better? Or are the larger fields still full of easy pickings in the early stages?
