The 2-tuner ChannelMaster DVR is $315 (currently at Amazon). Yes, you do not have to pay separately for the guide, but in reality, the guide costs are built into the device cost.
Here is some food for thought:
*The ChannelMaster is only a two tuner unit and thus comes in at $100 more than the 2 tuner Tablo. The ChannelMaster, like the Tablo, does not have built-in hard disk, so that does not account for the higher price. If you just add the $150 lifetime subscription onto the price of the 2-tuner Tablo, you will find that the Tablo is only $50 more expensive than the 2-tuner ChannelMaster (ChannelMaster does not have a 4-tuner equivalent to compare).
*The ChannelMaster must be connected to a TV and can only be used on that one TV (like the standard cable DVR). The Tablo can be viewed on any TV with a streaming box, as well as tablets, phones, and computers. Thus, you get a lot more flexibility for that additional $50.
*The Tablo lifetime subscription applies to all Tablo devices you own or will ever own. We have two 4-tuner Tablos, but only needed to pay the $150 once. So the second Tablo essentially has a free guide - as will any future Tablo we buy should technology change and a newer Tablo come out.
*There is no 4-tuner ChannelMaster. If you need to record/watch more than 2 things at once, you will need two ChannelMasters, which will operate independently of each other. When you buy that second ChannelMaster, the increased price still applies, so you are essentially paying for that guide again.
*ChannelMaster does not offer remote viewing period.
So, basically, when you compare 2-tuner models and you add in the lifetime subscription, the Tablo will cost $50 more, but for that $50 you will get multi-room viewing,viewing on mobile devices and computers, and you will never have to pay for the guide on any other Tablo product you buy. To me, that is $50 well spent. Add to that the ability to pay extra for a 4-tuner model, and the Channelmaster just doesn’t seem like a deal anymore.
If you buy the lifetime subscription, it is not really a monthly cost - just consider it part of the original price. Tablo could have bundled that pricing into its product, but that would force those who don’t want the guide to buy the guide. That also would prevent people from paying monthly for those who don’t think they will keep the Tablo for the 3-year break-even period. Tablo gives you options, Channelmaster just bundles the guide into their unit pricing.
