This is good advice in my opinion. Phrased somewhat differently, start as you mean to continue.
I've never owned a Lee press, but I'm under the impression that their aluminum framed presses may not be up to it in the long run, even though 6.5 CM isn't a hard case to resize, I'd call it about medium effort.
I do know the cast iron models get better reviews in general.
This is where the cost starts to creep in when you're first getting set up to reload. To keep the cost low initially, some manufacturers cut corners to get you into their products.
The initial saving turns sour if or when you have to replace the cheaper unit with one that'll do the job better in the long term.
I don't know how much weight you give to product reviews, but it can be a free insight as to what to expect.
RCBS is more expensive, you do however get what you pay for. Though I will say the on-press priming arrangement on the Rockchucker isn't worth the powder to blow it to hell. That's my personal experience.
For accurate shooting, try to pick one brand of brass and stay with it. Internal volume can vary from brand to another, which will affect pressure and therefore accuracy at longer range.
Good places to spend a bit more are on measuring tools and a scale, as well as the press itself.
I didn't buy a kit, but pieced together my gear from a mixture of new, used, and some stuff I built myself.
Best bet is to keep an open mind and weigh options carefully with an eye to potential resale and the long game.
