Lyman makes them for certain, and probably RCBS too. The Lyman one you would need for .35 Rem is their .35 caliber short model. The .35 caliber long would be suitable for .35 Whelan, .358 Norma Mag and such. You can get one directly from Lyman, or for less from Midway USA, Graf & Sons or similar suppliers.
Lee makes something called the universal expander die for about $10. It's just a flaring tool rather than an expander, but it's mighty close to being universal.
Lyman makes something they call a universal expander kit, too. Their version is a powder measure adapter with hollow expanders for the common pistol calibers. You have to shorten the stem to get them to work with rifle cartridges, but they do a good job with .30 and .35 calibers and let you save a step by charging as you flare.
