Go-lite are, alas, no more. Luxe outdoor do a few similar to the tee-pee style Shangri-las (like the Shangri-la 3):

If it's the twin-pole shape you're looking for, you could look at TarpTent, this one is somewhat similar:

I've no actual experience with either, I just like looking at tents online. I have a Shangri-La 3 that was my main hiking tent for a few years, and if you go with Tencakey's suggestion on eBay, I can certainly vouch for the quality. Beautifully made tents.
