How to choose a scoreboard?

Yesterday the leader of my team asked me to buy a portable electronic basketball scoreboard, I have no experience, and know little about that, oh, I know that is electronic equipment. Why is me? perhaps I dont play as well as Kobe Bryant....
What's worse, the budget is only $350, OMG. Hope kind buddies can give me some helpful advice. Thanks!

I don't know much about the subject either but the link below may help if you haven't already searched ebay.

Has someone ever purchased something from this site. After all prices of the site are fascinating, however, I feel it's too cheap to believe. Has someone purchased from the site, just Opentip. Thanks!

I have bought the scoreboard from the site, high quality, although a little slow delivery.
