Has anyone ever heard of Ehlers Longboards?

This is going to be long, but it's just so you all can understand. (I can't sum this up in two sentences, so please take a read!) I came across them on Facebook today, and I got super excited. Here's why. 1) my moms boyfriends kids (2 daughters that are my age and a 12 year old son) just discovered the beauty of this sport yesterday after Wisconsin decided to show us it's good side of its bipolar weather.. *tear* 2) I have four boards. 2 longboards, one penny board, and one shitty skateboard that my dad got me when I first discovered my love for skateboarding and longboarding shortly after. When we were skating, I was stuck with the skateboard. Why is it so shitty? Well, it vibrates like crazy and even when I'm at the skatepark it's so uncomfortable to ride. Idk whats up with it. The wheels? Trucks? I'm stuck. I've done everything I could. I'll post another card about it later. So the moral of the story is, I want to fix it up and sell it for like $50. My dad got it customized at a skate shop for $200 ish but it doesn't feel like what it's worth at all.. 3) if I do get my skateboard all fixed up and I end up selling it, I'd want to get a third longboard. It doesn't have to be super expensive, I'm just desperate for something better quality than my skateboard. I know that longboards and skateboards are different blah blah blah but mine shouldn't be this bad.. 4) Now after all of this explaining: has anyone ever got a board from Ehlers? I looked online and the prices are very surprising.. So I thought I'd ask to see how their quality is is anyone can give their opinion.

What board is more suitable for sliding?

This is, once again, a lengthy question. For 2015, my New Years resolution is to learn how to slide. I know, I know, for a dh rider I have everything else BUT the necessity of knowing how to slide! (Bring on the hate) these are my two boards. My madrid doesn't have much concave, but it's enough to keep me on the board...If that makes any sense. Plus there isn't any possible way for wheelbite, sooo yeah. But my other board, makes my feet feel more locked in. I took some pictures of my stance on both of them, (I'm goofy) as well as a shot of my mini zombie hawgs so you have an idea on what my setup would be. On my pintail I have caliber 2's, and on my madrid I have Paris v2's. I gave both of my boards' trucks a good flex today. They are relatively the same as for performance, so I don't think it would be much of a factor. (Or would it?) If you would have to pick one, which one would you choose? I'm leaning towards my Madrid, I'm just hoping that I wouldn't fly off. But I suppose I won't know until I try, right? Kind of off topic; I know squeaking is normal when you're not moving your board but you're standing on it and leaning back and forth, but my Madrid today was making this awful loud creaking sound. Like stepping on an old wooden floor. It's never been this loud before. I'll see if I can upload a video sometime so you guys can all hear it for yourself. I think it's just because my board is older, unless it could be something else. If you read all of this, I really appreciate it. I would've googled this but I don't think it would've been as efficient, since Google can't see my boards and all.
