Are Best's prices on the 7800 a good deal?

I've been wanting to pick a 7800 up for awhile as a space saver and I'm really tempted to pull the trigger on a Best 7800 with the mods (composite + their OS mod) but I'm not to sure if it's a good deal.  Seems like stock 7800s go for around $90-$100 on ePay with a stack of games (though almost always 2600 commons I already own).  

Is $140 for a modded 7800 fairly reasonable or would I be better suited by hunting for a deal?

How is Jinks? If I go with Best it'll be my only 7800 game for awhile.  Fortunately I've got my Harmony cart for 2600 games...
