You could go down the portable setup path and buy something that you can take with you. Handy if you want to go for a small drive to do some viewing. The 8" dobs these days are very easy to put into a car and take to a darker site.
My suggestion is to go along to an Astro society viewing night and check out what others use, you may find something you like. We could blow sunshine up your ... but at the end of the day its best to have a look for yourself and chat with locals who have been down the exact same path as yourself. . No doubt there are members on here which can give you some very helpful advice who livein similar spots.
Good luck with your search.
