Need suggestions for a used shell on 2001 tacoma

I am starting to look at a better setup for my Tacoma. I think with my tools maybe a shell is a good way to go for maximum storage that i can lock up and keep dry. I like the look and visibility of windows. i have to stick with a used one so availability is not all that great. How is working out of a truck with a shell and which ones would you recommend?

Eventually I would like to add like a light or medium duty ladder rack, maybe just 2 bars over the shell seems to be the lesser expensive option. 500lbs weight capacity would probably be plenty most of the time. This is also my only vehicle so its not just for work, ill be taking it out at night as well. Again I'm just looking for suggestions. Id rather spend a little more time shopping for the right shell then buying something I want to replace.

I did find a leer 100xl white fits my 2001 access cab for $550 from a truck cap distributor. Its got a nice look but it does not have the side windows that fold out. I think the folding side windows might be important for accessing tools, or does it not make much difference.
