I must explain something to you

I may be drinking. But I have always wanted to build a city adjacent to my whiteboard wall. A greyish city reminiscent of what Alderaan was before it got blown up. I am a poor mofo who doesn't have a lot of lego. I'm also not the best builder unless it comes to weird looking ships (I dismantled all because I realized all the pieces for my insectoids/roboforce things were all there and complete). I also want it to have classic space influences like...blacktron, insectoid and stuff, and I want it to look awesome and bright under a black light. How do I begin? Where? Where do I acquire grayish pieces at a cheap price? This is a walled city, like...a cliff y'know, but with stuff inside, and with a definite city shape. I want it to include a space for all 30 of my minifigs, a hangar for some of my ships, and a working elevator. AND A GRAND STAIRCASE. And an opening facade for it to act like a playset.

Your best bet is Bricklink.

I'm thinking I need a mesh up of black, grey, blue, red pieces for the outer structure, clear green and blue and red for glassware, and tech pieces for the inside and stuff. I mean, I could scan my drawings and stuff to show you what I wanna do. I mean, it's crazy.

Actually it's good to hear that you already have plans, that's a very good first step. It would really help if you could post your sketched drawings so people could post tips/advices to you. I'm no Sci-Fi expert but I might throw in my 2 cents once I see the sketches.

I guess your first problem will be to choose to stick to the old greys, new greys or mix the two of them.

If you choose old grays, you have to resort to second-hand bricks. Bricklink is good to find these old bricks in "near-new" condition. Alternatively, eBay is cheaper (especially for whole sets) but you will probably get many worn-out or discolored pieces.

If you choose new grays, you can get them new and cheap from the current sets, Kingdoms in particular (although I guess you'd want to resell the minifigs and medieval accessories).

I think many people would warn you against mixing the two, many AFOLs think they don't look good together.
