I'm not sure, I'm not familar with a flip top lid. I've heard of them but I have no clue what it is. You asked where to get Swap Magic.

I bought my PS2 Swapmagic DVD/CD with slide tool for $40 from Divineo.com It was shipped from Canada to the USA in only 4 days.

swap majic and flip top will work fine, just make sure you order it from a company that is in the US or Canada. I hear that some companies have had problems in customs and it holds up the order. i got mine here and had it in a few days. http://www.customps2.com/site/ ps2ownz.com has lots of great links for mod sites. that's where i found customps2.com

just get a mod chip i reccomend the matrix infinity. swap discs can wear uot your laser and dont work after 1-3 years. mod chips work between 20-30 years as long as your Ps2 is good. and the matrix infinity can also be upgraded from a disc you can download for free.
