+1 on trying Saison Dupont. It's fairly easy to find (although if you can get brown glass, do so. The green bottles I can usually find are skunked 90% of the time), and is one benchmark of the style.
Are you looking to do extract or all grain? You need to make sure it gets dry enough. Fairly easy with all-grain, can be a little tougher with extract since you can't directly control the fermentability.
I've never used Sorachi Ace myself (although had beers with em). My favorite combo is Styrian Goldings and Strisselspalt. I use a fair amount of late hops (primarily Strisselspalt), but I don't dry hop it. Other variants I'll go noble hops (Hallertau, Tettenang, and/or Saaz). I don't like American hops in Saisons usually, but that's just my preference.
As far as recipe, yeast strain is going to be everything. It's a very broad style with a lot of interpretation possible. Wyeast 3711 is a beast, will easily get almost anything to the appropriate level of dryness, and is easy to work with. However, I find its flavor profile to be so mild for a Saison yeast that it's almost mute. Danstar Belle Saison dry yeast would also be pretty easy to work with, and I think the flavor is a small step up from 3711, but not much. My preference is 3724 Belgian Saison from Wyeast, or the equivalent WLP565 Belgian Saison I from White Labs. This is the Dupont strain, and the flavor is awesome, however it's also notoriously hard to work with and is known for stalling out around 1.020-1.030. There's a bunch of other strains and blends available, including a number with wild yeast and bacteria that some folks are really fond of. Or you could culture from a bottle.
As far as grain bill, pils malt should be the main component. My go to is ~70% Pils, ~10% Munich, ~5% Aromatic, ~2.5% Carapils, and then the rest simple sugar. Corn sugar will work well. I like using a clear/blonde Belgian candi syrup (the syrup, not the hard rocks, don't waste your money on those). If you're doing all grain, mash low, maybe 147. If you're doing extract, you might want to up the sugar from 10-12% closer to 15-20%.
That's my 2c.
