Hmmm, I just checked online and I guess the XP3's are just going for crazy high amount right now :huh:
But to answer your question my first XP3 when I was brand new to the forum, from petsolutions.com for $95. Then when I found lots shop at big als and they had it for $88. Then last year I got one from petsmart when they had the big sale for $75 with free s&h. Maybe I should of bought a dozen of them and started selling them! lol. And yeah, as far as I am aware there is only 1 retail package and it includes everything but the bio media. Sorry, just seems like they jacked the prices recently, maybe they will go back down? Heck the classic eheims are probably cheaper than most places seem to be charging for the XP's.
