If you can afford only 5 ties for the rest of the year, I'd go used and pick up stuff from luxeswap or NWOT offerings on ebay and such. Ties are a relatively safe bet for these things.
Those all look gorgeous though!
I think neats will be hard to find on ebay and would lead to some settling. Something like chocolate and burgundy grenadines aren't really all that complicated and plenty of reputable makers make them.
Having 5 ties means that you're wearing every tie you own once a week.
4 of the 5 ties that poster linked to aren't all that complicated. Plain repp ties, unpatterned grenadines, and a simple pin dot.
