looking for a decent Router

Hi guys.
im wanting to spend less than £30 on a wireless cable DSL router and am looking the best signal range i can get from a router.
i have narrowed it down to 3:

Wireless N-Broadband
is supposed to have a good range.

is supposed to have a good range. according to linksys its this cheap because they messed up the firmware and that cheap price should help compensate for the hassle of upgrading firmware. after firmware upgrades recieved some good reviews.

dont know much about this router but has recieved some good reviews.
