Best way to get into the big tournies on Stars?

[illini43]

I have been interested in playing in the big Sunday tournaments on PokerStars for a while now.

I am wondering as to which is the easiest way to get into the big tournament.

My bankroll isn't as large as most 2+2er's but I feel like my level of play outweighs my current bankroll. I won my original money on Stars through a private freeroll with a cash pool, so I started at $30, now I am around $270.

Should I even attempt to get into the big tournament with my smaller sized bankroll? Is it worth it?
Should I stick to .25/.50 limit hold'em, the $1-$5.50 MTTs, and the $5.50-$6.50 SNGs until my bankroll is bigger?

Any help is appreciated.
