New $500 one-table NLHE SNGs on Stars

[M.B.E.]

I just noticed that Stars has a $500+30 one-table NLHE SNG listed in the SNG lobby. This must be pretty new. It seems odd that they're charging $30 rake when they have one-table PLOHL SNG's at $500+20. (Are those new too or have they been around a while?)

What I'm really curious about is how the $500 SNGs will compare to the $300 in terms of toughness. Will they make the $300s softer? tougher?

Stars also is now listing one-table "High Speed NL Hold'em" SNGs where the levels increase every five minutes rather than every ten. The stakes of the high speed SNGs interleave the existing NLHE stakes: $55+5, $25+2, and $15+1.
