Well, the OL Silver arm and Shelter 501 are both excellent products, and they will go a long way to ensuring good sound out of whichever TT you put them on.
You must bear in mind one of the cardinal rules of analog. That is, that in order of importance for sound quality, the TT is most important, the arm second, and the cartridge third. The lower you stoop at the TT level, the worse performance you will get out of the arm and cartridge that you have fitted.
A simple Rega RB250 with a Denon cartridge on a Teres or a TNT or a Verdier, will sound much better than the finest arm/cartridge combination in the world mounted on a Rega P3. The former package complies with analog hierarchy rules, and the latter violates it. Simple. This has been proven many years ago. Still holds true.
I recommend the OL Silver and Shelter 501 commonly here as very good items for the money. But they are not miracle-workers. The TT that you put them on will ultimately determine how good they will be overall. The better TT you put them on, the better sound you will get.
Following this hierarchy, the TT is the worst place to cut for budget. If you must cut for budget, the best place would be at the cartridge, and provide more money for a better TT. The cartridge is a wear item, and is expendable, while the TT/arm are not nearly so.
I'd recommend the purchase of either of the better TTs that you have listed, and cutting cost on the cartridge. Then step up to the 501 when it is time to replace the first cartridge. That is the sensible progression to take, and will ensure the best performance of the items you have purchased.
