The easiest "take my money" approach would be to look at some Troels Gravesen speakers on his website and/or find kits being sold on sites like parts express (if in the US). Jeff Bagby and Paul Carmody are two other well known designers, the latter having more budget-friendly builds. Additionally, sites like diyaudio.com are better when you want a specific thing built and are looking to learn more about techniques, new parts etc.
