I haven't used those HE Mavericks but they look on the soft side for rough terrain. I have a pair of HE Zulus which are more solid and doing well, better than I expected for the cost - slightly over your budget but not by much, I think they were $270 on sale.
As others have said though, Sarvo on this forum imports quality boots from Europe (which will probably last much longer than HE) and has some good deals.
