I just started using a straight myself. I bought an entry-level Dovo from VintageBlades. It's a 5/8" 1/2 hollow, round point. I also ordered one of their 3" strops. All Vintage Blades' razors come professionally honed and shave ready.
Vintages' Jim Ayars was terrific to deal with and was very helpful.
I really can't say how the Dovo compares to other razors as it's the only one I've ever used. It seems pretty good to me. More importantly, it got me started with a shave-ready razor for $79 (+sh) and the cost of the strop.
I don't mean to plug VB as there are likely other vendors who provide similar value and service. Just relating my experience and my choices to get started.
Good advice.
I started with the exact same set-up after shaving DE for a long time. VB is an absolute pleasure to deal with and the blade and strop were good choices. Still using the strop daily and the razor every couple of weeks. Needless to say that I've acquired lots of razors since then, but the Dovo was the one that made me know that straight razors are for me. Go ahead, take the plunge, you won't be disappointed. Know that once you get your feet wet, you'll be up to here in razors and accessories before you know it, but I'll bet you'll still be using the Dovo.
