They are not the most pricey either. Pricing is competitive with other similar offerings from Italy & Poland (for those of us in Europe).Boxem's amplifiers are indeed not the cheapest hypex based offering.
Offerings from France are indeed a bit cheaper, but the quality of the case alone is enough to justify the extra cost.
Not to mention that the guy is available here if you need him (I think his name is Frederic if I am not mistaken).
Just my opinion.
