Advice needed on Terrago Disc/ Fire mountain 2004

Hi All, I hope you can offer me some advice, as I'm pretty new to all this. I bought myself a Giant Terrago Disc back in September and had it for all of about a month and half before it was nicked from ouside Reading train station . Bit of a bummer as it was the 1st time I'd ever left it padlocked up outside. Anyways I'm really missing the thing now so I'll be going to get a new bike this weekend. Thing is, I've seen a good deal on a Kona Firemountain (2004) in the same shop, and I was wondering if it's worth getting that instead of another Terrago disc.

The Terrago was my 1st proper MB, and was a fantastic ride, so I'm kinda leaning towards getting another one. Just wondered if anybody has experience of the firemountain and can offer any info, or even suggest an alternative. I have a budget of about £400. Will the v-brakes be vastly different from the disc brakes?

I'm going to be using it mainly on roads/paths with some offroading btw. Thanks in advance for any help.
