First 7 String......

I've played that guitar a few times. Definitely worth the money imo. I'm also not a fan of floyds on 7 strings though, so that wouldn't be a drawback for me.
 
I just recently ordered an MH-417 which is definitely fun to play and great for the price. I didn't notice anything odd about the short scale length. The neck and body are both on the slim side and the EMG pickups sounded better than I have expected. I still had to send it back as it had some flaws that I didn't want to accept like a horribly glued nut, awful looking binding around the neck and it had some difficulties with adjusting the pickup height correctly. However I played another MH-417 from a different shop and it didn't have any flaws at all.

I then decided to order a Schecter Loomis after trying it out, which I recommend as an alternative. The neck and body are both just a bit thicker, which gives it a very solid feel. The guitar resonates beautifully and the build quality is great. It has absolutely no flaws and their models are definitely a step up from the LTD series guitars. The Loomis is also available with a Floyd Rose bridge and has a larger scale length. It's about $200 more than the MH-417.

Both guitars are fun to play and great for their price.
