If you want to start new, I would get a 30 or 40 gallon tank (with stand) If you have the tools and skill, make your own stand and canopy. (I spent 900 bucks on my 125 stand and it would of cost me over 1500 if I ordered it). You don't really need a sump for a 30 gal.
In my old 38 gallon I used a Coralife Super
skimmer. (rated for 65 gal)
I would suggest:
1xCoralife Super Skimmer (65)
2xKoralia Power Heads
1xTitanium Heater
(unnecessary) This is something you could add up later (upgrade) You could make a metal halide canopy and buy like a 150 or 175 watt single bulb ballast and make your own halides or if you don't have the tools you could buy a ready made one. (If you upgrade to like a 50 gal, you could still use the lights) (ready made is probably double the price depending on the brand)
All you really need is PC lighting, but the halides would probably make your SPS grow like crazy in a 30 gal. (I have three 175 watts in my 65)
A power filter is unnecessary, but I used to put one so I could put de
nitrate and
phosphate.

Sump:
You'll need a drilled tank or you could make one your self or you could buy an overflow box. If you want to make it your self
http://www.aquariumlife.net/projects...verflow/70.asp
I'm not sure how ti find the
GPH (forgot), but I'm sure other members could tell you
If you buy one, It should tell you how many GPH is required.
For the sump, get a 20 gal empty tank at petco and buy a sheet of acylic and cut them to make sections on your tank (get them cut and at local acrylic shop if you don't have tools)
1 st section is where the water goes down from the tank. Than the skimmer (i combined it with the first section) Then refugim and the last section is it gets pumped back into the tank.

I like sumps because they're better and you could have more choices for skimmers and you could have a nice refugim. (buying ready made sumps is ridiculously expensive. It cost me 100 bucks to make a 75 gal sump and it cost me 400 for a ready made 30 gal.
I would not get the coralife skimmer if you decide on a sump. There's better skimmers.
