You’ve given yourself a bit of a challenge here,
@Ste7 That is, if you’re exclusively looking for a boro device… Besides the two mentioned earlier (one not quite a box, and the other to be released “soon”), I know of only one other LiPo boro mod available right now (non-high end), and that’s the Sxk Delro:

But since that’s way over your budget, and it’ll take a couple of weeks to get there, it’s probably not in consideration
If you don’t care if it’s boro or not, you’ve already received a number of good suggestions… The Orion 2 has gotten a lot of raves here. Since I primarily use Nautilus coils when not using a rebuildable (1.0ohm mesh), I will mention that the Nautilus Prime is apparently still available here, though I can’t vouch for the vendor:

I wish you luck!
