>>7124121The other line is the Hi-Metal R, which is at the smaller 1/100 scale (makes a valk about 6 inches tall in battroid). Most HMR are from the original series, but they're starting to branch out as well. Transformations generally require some part-swapping, but the smaller size makes the valks pretty fun to handle. The biggest advantage, however, is that the smaller scale lets Bandai release a variety of Macross mecha besides valks. The HMR line has Zentradi mecha like Regults & Glaugs, plus there are Destroids too and they're all superbly done.
The smaller scale also make pricing more reasonable; a basic valk will cost you around $60, though most HMR valks include Super parts that bump the price to $90+. Pictured are HMR Max & Millia's VF-1Js.
The big disadvantage with Bandai stuff is that they're so popular that preorders almost always immediately sellout as soon as they open (especially with DX releases). There's usually some stock available on release, but that gets snapped up quick too. Also, releases for less popular valks or DX Super parts are generally web exclusive releases, which require you to purchase from through a middleman (easy to do, but just adds to the price). The spotty availability can cause skyrocketing prices on the secondary market, making it tough to catch up on releases you miss. If you can secure a preorder though, it's worth it.
There's a third company that is planning to release their own VF-1 in an unusual scale, but I can't remember what their name is. They're relatively unknown, having released some super deformed Macross toys, but they have yet to reveal a prototype or anything as far as I know.
There are some cheaper options for transforming valks, generally they're going to be from a company called Toynami or Kaiyodo's Revoltech line. I strongly recommend avoiding both. It's much better to save up and get an Arcadia or Bandai valk instead.
