I've always run with Cisco gear at work, so I figured, why not run with Cisco gear at home? Price is only a concern if you're buying new, and even when most people buy new, they don't buy at list price - they find a gold-certified reseller who can offer them up to 60% off Cisco list prices. Me? I bought most of my kit off eBay.
My own current setup is:
1x Cisco 1841 router with EHWIC-1ADSL for my broadband connection (this card supports ADSL2+)
1x Cisco Aironet AIR-AP1231G-E-K9 for wireless
1x Cisco Catalyst WS-C2940-8TT-S for a switch
The router was £60 off eBay. The WIC was £40 off eBay.
The switch was £40 off eBay. Sure, it's only a 100 Mbit/sec switch, but my internet connection is only around 10 Mbit/sec downstream. Works for me.
The wireless AP was £50 in a clearance sale from PCW Business - it was brand new in box.
If I'd bought an 1801, it'd have had an ADSL2+ interface built-in, but I wanted a router with a couple of WIC slots.
Total - £190. This ticks all the price boxes for me.
In terms of reliability - I've had the AP for a few years now and it's fine; the switch and router were more recent, and haven't let me down either. I've used all of these device types professionally for years (including in dirty warehouses, offshore oil platforms, and in Portakabins running off diesel generators), and have never had one fail yet, so I don't expect one to at home.
The 1841 isn't fanless, so it does make a small amount of noise, but it's not too bad (less noise than my peronal gaming desktop PC, but more noise than my Dell work laptop). It lives in my hallway next to the phone jack, so the noise doesn't annoy anyone. The 2940 switch and 1231 AP are fanless and run silently.
For server stuff, I've got a Raspberry Pi running Samba4 (for Active Directory), Cacti and Observium (for SNMP polling / graphing my Cisco kit), rsyslogd (for syslogging) and am currently pulling my hair out trying to get Horde Webmail to integrate authentication with LDAP. I also want to get a TACACS/RADIUS setup going.
