Hi jzkmom
My first bit of advice: search this forum for "filstar" and "XP1" and read all of the posts about these filters. It's what I did, and after a week of reading various people's experiences, I felt that I was able to make a good choice. I did finally decide on an XP1
I have the XP1 on my planted 20 gallon and generally have liked it a lot. While it does not have a button to push to self-prime the filter like the higher end Eheims (Professional series II), the filter itself is very easy to use. It comes with a basket for the media to go into, and it is divided in half so that you can put your biological media on bottom, then put the divider in, and then pile the carbon/mechanical media above that. Very easy.
HOWEVER, while my friend has had problems with his Eheim 2213 (mostly priming issues that nearly drove him mad), his filter can hold a TON of filtration media, while the XP1 holds suprisingly little. Sometimes I really wish that my canister could hold more, but my water seems ok, so I guess I really dont -- I guess its just filter-size envy. I use an HOB (hang on back) AquaClear 200 filter to do my mechanical filtering (I use 2 sponge pads instead of one, and then lay the carbon on top of them) while my XP1 handles the biological filtration (with the carbon insert inside as well). I use a combination of Filstar biomedia stars and Fluval bio-noodles for the bacteria colonies to grow on. My water seems very clear, and I have no complaints. Oh, I also put a cylindrical sponge "prefilter" on my inflow tube, so that no big particles go into the canister filter. I just wash off the prefilter once in a while and let the HOB do most of the mechanical filtering.
The XP1 comes with a spray bar that you can attach horizontally or vertically, and you can adjust the flow rate with a little valve. The inflow pipe and spray bars are a dark grey plastic, while the tubes going in/out of the filter are an opaque clear plastic.
I believe that the XP1 would be big enough for your tank, but you may want to go to their website and see the stats on the XP1 vs XP2.
www.bigalsonline.com is the place to buy them, their prices are SO MUCH CHEAPER than local fish stores.
I hope that helped. Please feel free to ask me any further questions you might have. I will dig out the URL to my imagestation album where I have pics of my XP1, in case you are curious.
Good luck
