Pretty much each blaster primary is similar in concept. Meaning each one has AOEs, PBAOEs and Range attacks. The secondary effects is what makes them different if anything. But at the end of the day a lvl 50 build is going to bring you the same results regardless if your a fire device or an assault rifle device. I have never turned away or been turned away because of the powers I picked. I can't even recall the last time I was on a team that didn't pick up someone because of their power choice. If they wanted a ranged attack player they didn't care what powers they were as long as it was range. Today with IO's you can pretty much fix any deficiencies an AT might have and more.
I posted several links in this post related to electric device. I would suggest you go and read those threads to get a better understanding of the device set and about defense cap and such.

Read that stuff download the builds and look at what you like. Swap out the primary for DP and post it up for inspection. Either way the links have probably 20 to 30 builds for you to choose from.

only played for a few weeks eeh.. i tried to make the cheapest possible build 
The Devastations and Trap of the Hunters will be expensive to craft.
If you wanna save money, buy lvl 39~45ish recipe's instead of lvl 50 (its not a huge % difference)
also the salvage requirements of recipe's changes depending on the lvl.
example: any recipe at lvl 40~50 will require different salvage for the same recipe at lvl 25~39.
btw, in some cases the crafted IO is cheaper than the recipe+slavage+crafting cost

perma jump is ---> /up 1
I'm new at this whole "MAKE A BUILD!" thing, so I was wondering if someone could just whip me up a basic 50s build for a DP/Dev Blaster. Something that won't cost me 10s of billions of inf, as a starting point.
The pools I selected/plan on selecting are:
Speed (Hasten)
Jumping (Combat Jumping, Super Jump) [Note: I was using Super Speed, but found that Super Jump is just SO much better]
Fighting (Boxing, Tough Weave)
Munitions Mastery (Body Armor, Surveillance, LRM Rocket)
I realize it might be a bit much for me to ask folks to whip up a build for me, but if I have something to work with early on I can tweak it from there. Well, that and I've only been playing CoH for about 2 weeks now and a lot of this is STILL new.
