i have the mercury. i bought it mainly because i live in philly, and frequented bike worx for my bike needs. i have ridden it every day for 9 months, and nothing has failed. however, it is really heavy. but, as a starter bike, i think it's alright. i know the hubs are basically considered crap, but my roommate (who has an alpha as well) and i have had no problems with them, skidding and all.

knowing what i do now, i would have definitely picked up a mercier. but since i live in philly and bike worx will fix small things on the alpha for free, i'm alright with the alpha. if you're in philly, it might be worth it just because you can go in if things start failing. for ordering online, i think the mercier would be the way to go.

ps. i have been lurking these forums for...oh about 8 months now haha. maybe now i will start posting.
