I saw this ad yesterday and i got the web site-http://www.MTEC.biz
APEX WANG'S CORP.
Address: No.3, Lane 12, Yazhou Rd., Tucheng City, Taipei 23677, Taiwan, R.O.C.

Anyone bought from them b4? Some say it still gives out error?
Why is it so cheap at only USD$162 for (10-50sets) and USD$220/set? is this true or not? why it sold USD$295 in US, what a big difference?

thanks
