Call for help - Cheap grails hosting for small apps?

Even though the rewrite of Brewerfan.net is in the forefront of my mind, the recent NFL draft has reminded me about how much I've been ignoring my other side venture, LambeauLeap.net. It's an app that I wrote in ASP.NET using DataTables and TableAdapters when I was told that they were the wave of the future *wretch*.

Now that I've seen how quickly and nicely I can write domain-driven apps with Grails, I'd really like to start from scratch with it, and give my staff and my users an app that doesn't feel like a lame afterthought.

The problem with Grails apps is that they have a pretty healthy memory floor. The other problem is that I don't really have the knowledge or the patience to learn how to administer a Linux box, which is the cheapest way to host a Java app if you need any kind of memory.

I really don't need a multi-node scalable solution like Mor.ph, which I'm using for Brewerfan.net. I'm looking at an app which at most will probably have 15-20 tables/domain objects and probably 50 pages. Anyone have a cheap-ish solution, which doesn't have me administering a Linux box from scratch?
