SEIKO T102 (ET-10) pocket TV

Guys,
I am looking for some info about a SEIKO T102 (alias ET-10) portable TV in excellent condition. Just wondering what a good price for this would be. I have it listed on EBay but think I might have it priced wrong. The listing is as follows:
SEIKO TFT Pocket Color Television Model No. T102, Hattori Seiko Co LTD, Made in Japan
Excellent condition with AC power adapter included.
A MUST for TV-collectors. The Seiko T102 (alias Epson ET-10) was the world's first commercial liquid crystal pocket color television (introduced in August 1984).
Unit includes foldable backlight unit, Audio and Video input jacks, headphone jack, 36 mm internal circular dynamic speaker, color/tint/brightness adjustments.
Screen Size: 2 inches
Pixels: 52,800
Dimensions: (W)160 x (D)80 x (H)31 mm
Weight: 450g (with dry cell batteries)
Power Source: 5 AA batteries, or 100V AC adapter
Reception range: VHF 1-12ch / UHF 13-62 ch

Any ideas?
Thanks,
Beth
