I have had the scope you current own for about 3 years. throw in a nice widfield eyepiece and go DSO hunting! your scope is up to it
you dont need to go teh EQ route but if kyou do be warned, it takes longer to set up and is alot heavier than the dob... I have put my scope on a HEQ5. if you click on teh link for my website in my signature yuo can see it.
