Yeah man there's plenty of bomb ass websites you can hit up for hardstyle and happy hardcore. Try checking out
http://www.imorecords.com It's all imported straight from the UK, which can get expensive, but I guarantee that you won't be able to find a broader selection of new happy hardcore any where else.
Also for other types of music, such as hardstyle, try out
http://www.dancerecords.com They provide a very large selection of every type of music (except happy hardcore
) for a fairly good price. + If you buy over $50 worth of records they have an option to make shipping free! Which is nice especially after you've been buying records offline for so long. (Shipping is a bitch :P)
