I just found this DTL-H2000 & DTL-H201A
Well i know you see this in other place like ebay, but this are never used. I wish i could buy this.
This items are been preserved in some place for over, how much? more than 15 years?

I spoke with this person explaining what they are worth to programmers/developers. It's a joke what collectors ask for 'rare' items. Where do they get their prices from?! They are new though, so I would say they are worth no more than ~$250. The H2000 on it's own is not worth more than ~$80.00 once used. I mean, come one. I got my H2000 for $60.00 USD
