I'm in a similar boat, Keith.
I can either get gamesforyous card and/or the naked TED.
or
Toilet Kids, Pastel Lime and Kato & Ken for about the same price CIB.
I have a decent collection of worthy PCE games right now. Even with my cheap UFO Pro 8 on my SNES, I can play all but 30 games on the SNES. I can play patched ROMS, homebrew (after padding/fiddle F-ing with the ROMS), and unreleased titles. Clocktower complete might be one of the only games I'd buy after getting this cart, and even then it's not enough to spend $40 on a display piece.
Honestly I see no need to expand my collections much further unless I want to display games. That said, if a CIB Splatterhouse/K&K goes on sale for the right price (see: below $20 for SH/$10 for K&K), I'll buy it.
Magical Chase is over-rated. It's yet another shooter, and a girly one at that. Just get both flash cards. One for general use, and GFUs card for SGX/natural play (since the TED won't fit in the SGX) where the game snaps on with no menus. They're both affordable enough (not like SD2SNES or ED64) to get.
