orion's are junk, and the bike in the first link (and every other on that site) is pretty much on the same level except it has a decent brand name lol... i think (but dont quote me) SSR once were a good brand, i think they sold to someone who didnt have a clue...
all brand names will have a junk model and some brand names will have all junk models...
if you can, raise your budget because at the end of the day you get what ya pay for..
and dont be scared to look at secondhand bikes, most the time youll get top brand name bikes at half the cost of new..sometimes less..
