I'm looking through BBS and considering whether I should buy a:-

1. New 12-14" foldie 'cos it's light
2. Used Jap foldie (I wonder if they are light)
3. Use others (RM1000-2000+)
4. Brand New (RM1500-3000)

It's so hard to choose. I think weight is important but I'm afraid of small wheels. I might need to cycle more and it might tire me as compared to 20-24" tyres.

Thoughts? Is it worth it to spend so much for a used/brand new? What are your thoughts on the Jap ones?
