I understand the want for a new piece of gear to sink one's teeth into. But do you really need it? You have everything you need in order to make the photographs you wish to make. You already have it. So, before you go sinking dough into something you don't really NEED, make sure first that you really need it. If not, just perfect your photography with the gear you possess.
From Cheryl's Article: Advice For Aspiring Photographers
It’s easier to focus on buying that next piece of equipment than it is to accept that you should be able to create great work with what you’ve got. Buying stuff is a convenient and expensive distraction. You need a decent camera, a decent lens, and a light meter. Until you can use those tools consistently and masterfully, don’t spend another dime. Spend money on equipment ONLY when you’ve outgrown your current equipment and you’re being limited by it. There are no magic bullets.
