...budget of 1500, can anyone help a beginner out with some recommendations?
I realize that this is taking your request for recommendations and willfully misconstruing it, but stick with me!
Visit RFDs. Handle as many different centrefires as you can - even ones that aren't 243, because the chances are that if you find a 308, 6.5 Creedmore etc that fits you well and that is comfortable to manipulate, you'll be able to track down the same thing in 243 anyway. If there are opportunities to shoot different styles and makes, take them.
The brand or make of rifle is a useful guide but no real guarantee of anything very much. There are lots of very well made rifles that are very inexpensive because they are unfashionable or out of production. 1500 is a huge budget for a first deer rifle and should see you set up with a rifle, sling, slip, scope, mod and decent quantity of ammo so long as you aren't too susceptible to marketing BS and brand snobbery.
I'm not saying that you shouldn't buy nice things, but there are definitely points of diminishing return - a Tikka T3 is absolutely a "better" rifle a Savage Axis, but it's not necessarily more reliable, and probably isn't any more accurate. Lot's of people slag-off Howa rifles, which is pretty dumb as it's basically a reverse engineered Sako built with the same industrial philosophy that produced the Toyota Hilux.
I would look for mid-tier brands and items and try and husband as much of the budget as possible into opportunities to stalk and opportunities to practice your shooting - you don't need a German rifle with Austrian glass, Swedish ammo and a titanium moderator to shoot accurately and kill deer, because I promise you can do it all with an American rifle, Japanese glass and Serbian ammo - and there's a decent chance you'll shoot smaller groups and kill more deer too.
