To be honest Cdr you can get a pretty good explorer Asp for 16million. Currently flying a 16mil build Asp back from the core and she's performed amazingly.
Used to fly the DBE. Great ship. Cheap as well but limited. You get that nice class 6 scoop and tons of module space in the Asp you just don't get in a DBE.
30 mil will get you a great Exploring Asp.
My own 16 mil credit explorer build is here. Tried and tested and worthy:

6C fuel scoop is surprisingly good, don't waste your cash on a 6A (28 mil!) and AFMUs are vital in my opinion if you are going to explore deep.
I am upgrading when I return, and my upgrade is just short of 30 mil (29 mil actually) it is as follows:

Dropping an AFMU for the upgrade to 5A, upgrading my fuel scoop to a 6B and I feel we will need cargo space as explorers post 1.4
Or you could go DBE, but I wouldn't recommend downgrading from an Asp, especially if you have the cash. The Asp is just a far superior explorer. I used to explore in a DBE, here is my old DBE for comparison:

Similar price, almost similar range but the modules let it down. You need a good fuel scoop, a good FSD and solid module adaptability out there and in my opinion the DBE just doesn't offer it.
Saying that other Cdrs swear by them. I am a numbers geek and to me the numbers in DBE builds just don't compare to the numbers in a similar spec Asp. Especially when you consider my 16mil Asp build is still upgradable whereas my old 16mil DBE build was maxxed out.
Happy to advise but I am but one opinion.
Take care and good luck Cdr.
