Behringer bass stuff does look great for the price - but there's a saying - you remember the quality but forget the price. As soon as you buy that cab, it'll drop in value by at least half, if not more. You'll then be left with the cab. You may love it, chances are you'll feel you could have done better. By all accounts they're heavy and made on a tight budget.
You'd be better off buying secondhand I think - something better quality. Spend £100 on an Ashdown, Warwick, Hartke or similar cab and you be happier in the long run, I reckon.
