How about inexpensive? I know it's semantics, but there can be a huge difference between inexpensive and cheap! <:-)) I recently saw a group raving about some of these super expensive status symbols, when the real auto enthusiasts were referring to them as maintenance hungry, expensive POS. <LOL>

When it comes to ham gear, and this has shown up on a number of amplifier news groups:

Only in the past few years has IMD even been addressed for top end rigs. They are dealing with astounding receiver specs that have long passed the point of being useful on HF when the majority of problems arise because the signals are in the realm of being a POS. Yes, dynamic ranges are terrific when a station 20 or 30 KHz up, or down is 20 or 30 over. Yet it will do nothing if the station 20 KHz up, or down is over driving the amp with leading edge spikes making the signal 30, or 40 KHz wide. Yet there are hams who seem unable to understand why they hear a station 10 KHz up that is only S9 or 10 over (with IM3 of only 30 db) After all, the specs show that is well outside the bandpass of their filters. Only recently have signals from "top end" and expensive rigs even "APPROACHED" the quality of the old Collins S-Line and they brag about an IM3 of 40 to 45 db.

Cheap Vs inexpensive should be a no brainer when I can purchase a used F12 C19XR for $500 completely disassembled and well marked (which I did). I only need to clean the joining sections, coat with Noalox, or other conductive grease for Aluminum and install new rivets. If I want to take the time, a fine Scotch Bright pad will have it shining and a coat or two of clear Krylon will keep it that way for a few years.

Towers as well can be found used and with the exception of light duty towers like the 25G (stay away from the really cheap stuff). You might have to hunt, but there are a lot of bargains in used crank ups. After all, to take a crank up, down usually involves removing a few bolts.

I'd like to replace my 10' 45G with a heavy duty crank up that'd go, 90, or 100 feet. Those are not as easy to find, nor are they cheap.

Used is often the most bang for the buck by far, if the product is in good shape.

If you want cheap and GOOD, do the design, buy the parts, and do it yourself. Or buy quality used. My neighbor, W6GJB, has bought a couple of Force 12 C3s cheap, rebuilt them, and has superior antennas. I've bought used vintage rigs for a fraction of their new cost, like the TS850.

There are lots of ways to save money that aren't CHEAP.
