That is much more expensive than electric fencing equipment and on par with the mid priced 2.0.mm machine made bogu (mine was about 650.00).
That will definitely have an effect.
Just for comparison, saber fencers get the costliest gear, as they need an electric mask, jacket, wire, and I think a special glove, plus the saber. Altogether, you're looking at about 400. for everything as I recall.
Foil, which is by far the most popular of the three fencing weapons, requires a lame, a wire, and an electric foil, which together are less than two hundred on top of the normal protective gear (non electric mask, glove, jacket, and knickers), which can be had for as low as about 200. Several manufacturers make electric starter sets that will cut the costs even further.
Epee requires only an electric epee and a wire. Less than a hundred unless you want maraging steel.
Sounds like a hefty chunk of money, especially if, as you pointed out, you have a child who is likely to grow out of it.
